Completely agreed. What I would say is that Dune Messiah is a very tricky beast to turn into a film as compelling as the first two. However, my understanding is that Villeneuve is going to do more than adapt Dune Messiah (a relatively slender volume). He's going to adapt some elements of Children of Dune as well, which is a much meatier prospect. I'm curious to see how this will work, but if anyone can pull it off, he can. And I think (knowing the ultimate ending for all concerned) there is certainly potential. It may upset some of the purists, as it will require certain omissions and reinventions, but... Well, I'm sure we'll find out soon enough. :)
